什么是 Critical taper？

Definition 10.4 University Earth and Space Sciences — Year 3 · 第 10 章 — Thrust Belts and Orogenic Wedges

The critical taper of a wedge pushed from behind over a base is the taper at which the wedge is everywhere on the verge of failure, inside and along its base, under horizontal compression. A wedge at its critical taper slides over its base without deforming internally; a wedge below it (subcritical) deforms and thickens until it reaches it; a wedge above it (supercritical) slides without deforming.

A wedge of surface slope resting on a décollement of dip and pushed from behind; x is measured from the toe towards the hinterland. On a vertical slice, the push F(x + dx) from behind exceeds the push F(x) from the front by what the base takes: its friction _b and the horizontal part of its normal stress _n, which leans towards the hinterland on a base dipping that way (schematic, angles exaggerated). — A wedge of surface slope $\alpha$ resting on a décollement of dip $\beta$ and pushed from behind; $x$ is measured from the toe towards the hinterland. On a vertical slice, the push $F(x + \mathrm dx)$ from behind exceeds the push $F(x)$ from the front by what the base takes: its friction $\tau_b$ and the horizontal part of its normal stress $\sigma_n$ , which leans towards the hinterland on a base dipping that way (schematic, angles exaggerated).

Critical surface slope against basal dip for the friction coefficients of western Taiwan, = 1.03 inside and _b = 0.85 on the base, for three pore-pressure ratios = _b; “subcritical” and “supercritical” refer to the = 0.7 line. The shaded bands are the tapers of the Jura thrust wedge, 3 to 4, and of the wedge to its south, 12 to 13. — Critical surface slope against basal dip for the friction coefficients of western Taiwan, $\mu = 1.03$ inside and $\mu_b = 0.85$ on the base, for three pore-pressure ratios $\lambda = \lambda_b$ ; “subcritical” and “supercritical” refer to the $\lambda = 0.7$ line. The shaded bands are the tapers of the Jura thrust wedge, 3 to $4{}^{\circ}$ , and of the wedge to its south, 12 to $13{}^{\circ}$ .
